As you can see, I mounted the new assembly to the upper access door frame. I mentioned the upper baffle that I added and you can see it in the first pic below. Again the reason was to ensure that as hot air exited the condensor area, it travelled immediately to the outside via the door louvers.

The last baffle is to ensure that the hot air short circuit is not possible and you can see it in the last pic below. I simply cut a panel of sheet aluminum to fit the area below the fan bracket. Now I can be assured that all the incoming air is from the lower access door louvers. I also sealed the lower section of this baffle with silicone sealant as I have noted rain can blow in and collect in the lower section of the door frames.

I did not mention that I removed the original on/off switch and replaced it with a DPDT toggle switch mounted in the horizontal support bracket. This is a center position off switch, so I can switch from parallel to off to series modes. I have actually thought about adding a led indicator so that I can tell if the fans are running as they are so silent.

Sorry if this turned into a dissertation, but I wanted to provide sufficient detail so that others that wanted to duplicated my efforts would understand how, what, and why.

Lastly, I had the opportunity to field test the new design over the Memorial Day weekend. The daytime highs were in the lower 90s and I found the fans cycling on and off during the day, something the old design NEVER did. I also noted that the fans shut down shortly after sunset, again something that used to take an hour or two with the old design. These observations were made with fans running at full speed. I never switched them to series/half speed as I wanted to understand how well they worked and how much noise they created. I also measured the current drawn...in series mode, about 90ma, in parallel, about 260ma, meaning about 1/4AH MAX.
